Answer:
B. Negative
Step-by-step explanation:
We are given that x equals negative and y equals positive.
That means the fraction is negative multiplied by the 7y³ term, which is positive.
Negative times positive is negative, so B is our answer.
<h2>true</h2>
I did it on my calculater and the answer came as 13
hope that helps :)
The line crosses the y-axis at y=4, so will have an equation of the form
... y = (something)·x + 4
The line rises from left to right, so has a positive slope. That is, the "(something)" must be greater than zero.
The only selection that meets these criteria is
... B y = 2x + 4
Answer:
y = 3
Step-by-step explanation:
We need to find the slope. We do so by choosing any two points and dividing the change in the y-coordinates (their difference) by the change in the x-coordinates (their difference). Let's just choose (1, 3) and (0, 3). The slope is: . So, the slope is 0.
We want to write a line in slope-intercept form, which is: y = mx + b, where m is the slope and b is the y-intercept (where the line crosses the y-axis). Here, the slope m = 0. Looking at the graph, we see that the y-intercept is (0, 3), so b = 3. Then, our line is: y = 0x + 3 ⇒ y = 3.
Another note is that this is a horizontal line. One thing to remember is that all horizontal lines have slopes of 0, so their function is simply y = k, where k is a constant through which the line cuts through.
Given:
The shaded sector above covers 
of the circle.
Radius of the circle = 3 cm
To find:
The area of the sector in terms of π.
Solution:
The area of a circle is
Substituting 
, we get
It is given that the shaded sector above covers of the circle.
The area of shaded sector 
Therefore, the area of shaded sector is 3π sq. cm.
